xxProbe length times 2 (probe length is the length in inches from bottom of the hex to bottom of the device)

Field 3

xxxOperating characteristics, assigned consecutively (Sensata will assign this number at the time your order is taken)

Field 4

xxFor wire leads, this is the length of wire in 6 inch increments (for 6" it would be 1, for 12" it would be 2, for 18" it would be 3, etc.). For connectors, contact Sensata Technologies for this code.

So, a ¾" - 16 thread with connector (see "Standard Part Numbers and Configurations" at right) with probe length of 3" and with an 18" wire lead would be numbered: 21546-06-xxx-03.

-65°F to 400°F (-53.9°C to 204.4°C)Maximum ambient exposure should be limited to 100°F above operating temperature for close on rise devices or 100°F below the operating temperature for open on rise devices.

Operating Temperature Range

0°F to +275°F, (-17.8°C to 135°C)

The standard operating temperature ranges, differential and tolerances are shown in
the table below, but can be customized to meet your specific requirements.

Configurations

Standard narrow differential probe packages are comprised of the following physical features, but many other variants are available to meet your needs.

PLEASE NOTE: The orientation of the connector with respect to the package body is not controlled.

Configuration Options - Custom configurations are available
